Example 1: Convert String to Date using predefined formatters
import java.time.LocalDate; import java.time.format.DateTimeFormatter; public class TimeString { public static void main(String[] args) { // Format y-M-d or yyyy-MM-d String string = "2017-07-25"; LocalDate date = LocalDate.parse(string, DateTimeFormatter.ISO_DATE); System.out.println(date); } } Output
2017-07-25
In the above program, we've used the predefined formatter ISO_DATE that takes date string in the format 2017-07-25 or 2017-07-25+05:45'.
The LocalDate's parse() function parses the given string using the given formatter. You can also remove the ISO_DATE formatter in the above example and replace the parse() method with:
LocalDate date = LocalDate.parse(string, DateTimeFormatter);
Example 2: Convert String to Date using pattern formatters
import java.time.LocalDate; import java.time.format.DateTimeFormatter; import java.util.Locale; public class TimeString { public static void main(String[] args) { String string = "July 25, 2017"; DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM d, yyyy", Locale.ENGLISH); LocalDate date = LocalDate.parse(string, formatter); System.out.println(date); } } Output
2017-07-25
In the above program, our date is in the format MMMM d, yyyy. So, we create a formatter of the given pattern. Check all DateTimeFormatter patterns, if you're interested.
Now, we can parse the date using LocalDate.parse() function and get the LocalDate object.
